Composition and process for color hair

ABSTRACT

A composition, kit and process for dyeing hair fibers in a manner which inhibits color loss during subsequent shampooing involving contacting the hair fibers with a composition containing: (a) at least one polyamine having at least two amino groups; (b) at least one anionic silicone; and (c) at least one dye component chosen from a direct dye and an oxidation dye, and wherein the dyed hair fibers inhibit color loss resulting from subsequent shampooing of the dyed hair fibers.

BACKGROUND OF THE INVENTION

The present invention relates to a composition and process for coloring hair. There are essentially two ways in which hair fibers may be dyed: “permanent” dyeing and “semi-permanent” dyeing.

The first, also known as oxidation dyeing, uses “oxidation” dye precursors, which are colorless or weakly colored compounds. Once mixed with oxidizing products, at the time of use, these precursors lead to colored compounds and dyes via a process of oxidative condensation. In this case, the colorations obtained are generally very colorfast and strong.

The second, also known as direct dyeing, uses direct dyes, which are nonionic or ionic dyes and colored compounds capable of producing a more or less pronounced change of the natural color of the hair, resistant to shampoo-washing several times. These dyes may or may not be used in the presence of an oxidizing agent.

In contrast with oxidation dye precursors, a direct dye is a relatively voluminous molecule that does not penetrate easily into the core of the fiber. Consequently, even though considerable progress has been made in this field, the phenomenon of bleeding of the coloration, i.e., color loss, during shampooing is still non-negligible, even if the dye(s) used is (are) chosen from cationic species. Moreover, the use of certain cationic direct dyes may be reflected by a reduction in the working qualities of the shampoos used after coloration, especially as regards the duration of the lather.

While the phenomenon of bleeding of the coloration during shampooing is more pronounced when direct dyes are used, this phenomenon occurs when oxidation dye precursors are employed as well.

Thus, one object of the present invention is to provide a composition and process for dyeing hair in a manner which inhibits color loss resulting from subsequent shampooing of the dyed hair fibers.

SUMMARY OF THE INVENTION

In order to achieve these and other advantages, the present invention is drawn to a hair dyeing composition containing:

-   -   (a) at least one polyamine compound having at least two amino         groups;     -   (b) at least one anionic silicone; and     -   (c) at least one dye component chosen from a direct dye and an         oxidation dye.

The present invention is also directed to a process for dyeing hair fibers in a manner which inhibits color loss resulting from subsequent shampooing, involving contacting hair fibers with the above-disclosed hair dyeing composition.

Surfactants

It may be desirable, in certain circumstances, to employ a surfactant such as, for example, a nonionic surfactant, an anionic surfactant, an amphoteric/zwitterionic surfactant, and a cationic surfactant.

Suitable nonionic surfactants are any suitable nonionic surfactants that have an HLB of from about 3 to about 14. The abbreviation “HLB” stands for hydrophilic lipophilic balance. Examples of suitable nonionic surfactants include, but are not limited to, fatty acid esters and alkoxylated, particularly ethoxylated, fatty acid esters of polyhydric alcohols such as glycerols and sorbitol, for example, polyoxyethylene monolaurate, polyoxyethylene monooleate, polyoxyethylene monostearate, sorbitan monolaurate, sorbitan trioleate, generally with a degree of ethoxylation of from about 20 to about 85; mono- and di-alkanolamides, such as the N-acyl derivatives of mono- and di-ethanol amines, and polyethoxylated monoalkanolamides; amine oxides, such as cocoamidopropyl dimethylamine oxides, coco bis-2-hydroxyethyl amine oxides and lauryl dimmethylamine oxide; ethoxylated alkanolamides; ethoxylated oils and fats such as ethoxylated lanolins; and ethoxylated alkylphenols, such as Nonoxynol.

Suitable anionic surfactants include, for example, the following: the alkali metal, ammonium, or amine salts of alkyl sulfates, alkyl ether sulfates, linear alpha-olefin sulfonates, dialkyl sulfosuccinates, alkylamidosulfosuccinates, and alkyl taurates each having from about C₁₂ to C₁₈ alkyl or alkenyl groups. Particularly preferred are the salts of lauryl sulfates and lauryl ether sulfates the latter having an average level of ethoxylation of 1-3.

Amphoteric/zwitterionic surfactants belong to the category of surface active chemicals that possess a positive and a negative charge in the same molecule and behave as a cation or an anion depending on the pH of the medium. In general, the positive charge is located on a nitrogen atom while the negative charge is carried by a carboxyl or sulfonate group.

There are a large number of amphoteric surfactants that are suitable for use in this invention. They include, for example, lauryl betaine, lauroamphoglycinate, lauroamphopropylsulfonate, lauroamphopropionate, lauroampho-carboxyglycinate, lauryl sultane, myristamidopropyl betaine, myristyl betaine, myristoamphoglycinate, myristyl propionate, stearoamphoglycinate, stearoamphopropionate, stearoamphopropylsulfonate, stearyl betaine, cocamidoethyl betaine, cocamidopropyl betaine, cocamidopropyl hydroxysultane, cocamidopropyl dimethylamine propionate, cocoamphoglycinate, cocoamphocarboxypropionate, cocoamphocarboxyglycinate, coco-betaine, cocoamphopropionate, cocoamphopropylsulfonate.

The amphoteric surfactants presently preferred for use in this invention are: cocamidopropyl betaine, cocobetaine, stearyl betaine, cocoamphocarboxyglycinate, cocoamphodipropionate, and stearoamphoglycinate.

The lotion may contain organic solvents to assist in dissolving the dye precursors. However, it has been observed that in the compositions of this invention, the organic solvent content should be kept at a minimum. More solvent than is necessary to dissolve the precursors may have the effect of retarding diffusion of the precursors into the hair for reaction.

Typically useful solvents include alcohols containing up to three carbon atoms such as ethanol and isopropanol, polyhydroxy alcohols such as propylene or hexylene glycol and lower alkyl ethers thereof such as ethoxy ethers.

Other conventional agents often employed in hair coloring compositions may be employed in the lotion or in the developer. These include, for example, fragrances, coloring agents and chelating agents. Antioxidants such as sodium sulfite erythorbic acid and ascorbic acid may also be included to inhibit premature oxidation.

The oxidizing composition or developer employed in the invention is an acidic aqueous composition which comprises the selected oxidizing agent together with one or more anionic polymers which are insoluble in water.

The preferred oxidizing agent for use in the developer of the invention is hydrogen peroxide although other peroxides may be employed. These include, for example, urea peroxide, melamine peroxide, perborates and percarbonates such as sodium perborate or percarbonate.

The lotion and developer are mixed just before application to the hair. On the hair, they form a stable gel with enough consistency and body to remain on the hair during the complete coloring period without dripping or running. The primary intermediate and coupler, i.e. the dye precursors diffuse rapidly into the hair together with the oxidizing agent. The dyes form within the hair fiber and, since they are large molecules, remain in the hair so that the color change is permanent. The term “permanent” means that the dye does not readily wash out of the hair with ordinary shampoos. The color achieved with the products of this invention is so stable that it may survive as many as 10 shampooings without noticeable change.

Conditioning agents may also be employed in the direct dye and oxidative dye composition(s) so as to impart added conditioning benefits to the composition. The conditioning agents useful in the present invention are those which are dispersible in water and typically may be chosen from cationic surfactants, silicone compounds, polyalkylene glycols and mixtures thereof, preferably mono long-chain ammonium compounds, hydrophilically substituted cationic surfactants, hydrophilically substituted silicone compounds, polyalkylene glycols, and mixtures thereof.

The type of conditioning agent selected depends on the desired characteristics of the product. Highly water soluble conditioning agents are typically used. A combination of conditioning agents is preferably used to provide benefits provided by the different conditioning agents. Conditioning agents which are less water soluble can be used in combination with highly water soluble conditioning agents.

Cationic surfactants may be used as conditioning agents herein. Suitable cationic surfactants useful herein include, but are not limited to, those generally described as mono long-chain ammonium compounds. Nonlimiting examples of such cationic surfactants include: cetyl trimethyl ammonium chloride available, for example, with tradename CA-2350 from Nikko Chemicals and CTAC 30KC available from KCI, stearyl trimethyl ammonium chloride with tradename Arquad 18/50 available from Akzo Nobel, hydrogenated tallow alkyl trimethyl ammonium chloride, stearyl dimethyl benzyl ammonium chloride, stearyl propyleneglycol phosphate dimethyl ammonium chloride, stearoyl amidopropyl dimethyl benzyl ammonium chloride, stearoyl amidopropyl dimethyl(myristylacetate)ammonium chloride, and N-(stearoyl colamino formyl methy)pyridinium chloride.

Also preferred are hydrophilically substituted cationic surfactants in which at least one of the substituents contains one or more aromatic, ether, ester, amido, or amino moieties present as substituents or as linkages in the radical chain. Nonlimiting examples of hydrophilically substituted cationic surfactants useful in the present invention include the materials having the following CTFA designations: quaternium-16, quaternium-26, quaternium-27, quaternium-30, quaternium-33, quaternium-43, quaternium-52, quaternium-53, quaternium-56, quaternium-60, quaternium-61, quaternium-62, quaternium-70, quaternium-71, quaternium-72, quaternium-75, quaternium-76 hydrolyzed collagen, quaternium-77, quaternium-78, quaternium-79 hydrolyzed collagen, quaternium-79 hydrolyzed keratin, quaternium-79 hydrolyzed milk protein, quaternium-79 hydrolyzed silk, quaternium-79 hydrolyzed soy protein, and quaternium-79 hydrolyzed wheat protein, quaternium-80, quaternium-81, quaternium-82, quaternium-83, quaternium-84, and mixtures thereof.

The polyalkylene glycols useful herein as conditioning agents include those which are soluble or dispersible in water. Polyethylene glycols are preferred.

Polyalkylene glycols having a molecular weight of more than about 100 are useful herein. Ethylene oxide polymers are preferred in view of their generally good water solubility, dispersibility, and transparency. Polyethylene-polypropylene glycols and polyoxyethylene-polyoxypropylene copolymer polymers having good dispersibility and transparency may also be useful. In the above structure, x3 has an average value of from about 4 to about 600, preferably from about 6 to about 120, and more preferably from about 10 to about 40.

The composition(s) of the present invention may also comprise additives, for instance those chosen from the non-exhaustive list such as reducing agents, antioxidants, sequestering agents, softeners, antifoams, moisturizers, emollients, basifying agents, plasticizers, sunscreens, direct dyes or oxidation dyes, pigments, mineral fillers, clays, colloidal minerals, nacres, nacreous agents, fragrances, peptizers, preserving agents, fixing or non-fixing polymers, proteins, vitamins, antidandruff agents, aliphatic or aromatic alcohols, and more particularly ethanol, benzyl alcohol, modified or unmodified polyols, such as glycerol, glycol, propylene glycol, dipropylene glycol, butylene glycol or butyl diglycol, volatile silicones, mineral, organic or plant oils, oxyethylenated or non-oxyethylenated waxes, paraffins, fatty acids, associative or non-associative thickening polymers, fatty amides, fatty esters, fatty alcohols, and the like.

The method of the invention comprises applying the dye (direct or oxidative) to the hair to be colored and allowing it to remain in contact with the hair until the desired hair color has been attained after which the composition is removed from the hair.

The present invention will be better understood from the examples which follow, all of which are intended for illustrative purposes only and are not meant to unduly limit the scope of the invention in any way.

EXAMPLES

Bleached hair swatches were dyed with a coloration composed solely of basic/Arianor or chromatic dyes. The chromatic coloration, Redken Color Fusion Hi-Fusion R, was mixed in a 1:1 ratio with Redken Pro-oxide 20 volume Cream Developer and remained on the hair for 30 minutes, whereas the basic coloration, Matrix Prizms Light Auburn, was applied as is and remained on the hair for 20 minutes. Swatches were rinsed with warm water for 25 seconds. In another set of hair swatches, the Polyamine/Amionic Silicone was added to the color cream prior to application to hair. Following the coloring process, the initial L*a*b* value of the colored hair swatches were obtained. The swatches were shampooed seven consecutive times with a 15% SLES-2 solution (pH 6.35). Specifically, 0.4g of SLES-2 solution per 1 g of hair was applied, massaged into the swatch for 15 seconds, and rinsed with warm water for 10 seconds. After at least 7 shampoos, the swatches were blown dry and the final L*a*b* values were obtained. The ΔE* value, representing the total color change was calculated using the following formula: ΔE*=[(Δa*)²+(Δb*)²+(Δc* )²]^(1/2)

Swatches were treated in triplicate with one of the following colorations:

-   A: Coloration without PEI/Silicone Phosphate -   B: Coloration with 1.0% PEI and 0.5% Dimethicone PEG-8 Phosphate -   C: Coloration with 3.0% PEI and 0.5% Dimethicone PEG-8 Phosphate -   D: Coloration with 5.0% PEI and 0.5% Dimethicone PEG-8 Phosphate

All reported concentrations are percent active rather than as is.

After 1 dye out and at least 7 shampoos, statistically significant improvement in color retention was observed for swatches that were dyed with mixtures B, C, and D compared with those swatches dyed with the coloration without PEI/Silicone Phosphate (A). Table I displays the resulting ΔE* values.
